Hi guys , i just joined this forum yesterday . i asked toykeeper some questions yesterday regarding the emisar d4 as im planning to get a few to use for work and edc . toykeeper directed me here . thought i would ask everyone here about it . i do apologize in advance if some of my questions seem stupid as im no expert on flashlights .
1)is the emisar d4 durable enough for work and edc(i work in construction so dropping it on the ground and puddles of water will be inevitable)
2) i usually use 250-600 lumens max on my previous lights so what kind of runtimes can i expect from the d4 if i use it that way(the 3000+ lumens of the d4 makes it nice to have even if i wont need to use it often)
3) how long of a lifespan can i expect from the light itself ? Eg. The led .
I can’t answer all of those, but here’s at least a partial answer.
The light uses 350mA at the ~150 lm level, so it probably uses about 2 to 4 times as much power at the 250-600 lm levels you described. Maybe 700 to 1400 mA, which on a 3000 mAh cell works out to about 2 to 4.5 hours.
The LED itself is unlikely to ever burn out or need replacing, especially if you have the XP-L HI model. I hear the Nichia 219c may have some difficulty when used at turbo a lot, but it should generally still be fine for normal use. The main thing people have reported issues with is a broken switch wire. But that will generally show up right away, and shouldn’t really degrade over time. Or a couple people have managed to break the lens, but it’s pretty easy to replace.
I studied the Samsung spec sheet, learned the reasons for all the lettering and text in their label, and that’s what I go by. The Digi-Key in the US doesn’t sell the 90 CRI 5000K in singles. The 80 CRI ones I bought were $2.64 each as compared to $3.57 or so Canadian on the links posted above for the 90 CRI version. The Canadian site also has W6 power bins available that the US store doesn’t have at all. Now if we could only find the 96 power bins…
I won’t buy an S6 power bin when W6 is the current highest available. 4 levels down in power, no thank you.
Edit: And following that last provide link shows a W6 in the US store, Digi-Key is SO confusing… I’ve spent hours in their store in the past few days and bookmarked the highest bins, searched it out all over again a few minutes ago and U6 was it, now that link shows differently, how I don’t know but there must be some discrepencies in their warehouses or something and it’s frustrating. lol
